To al! whom it may concern.'

Bc it known that I, 1WILLIAM G. Vi'icu'r, e citizen of the United States ol ilin'iericn re siding:r et Yule, in the countjiv oi St. (flair und State ol Michigan, have invented certain new and useful Improvements in Sectional Conduits, of which the following; is n spcciiicalion, reference being had therein to the accoinpnirving drawings.

The invention relates particularly to nie tniiic sectional conduits, and consists primai-iiiv in means for coiniecting or joining the nburl ini:r sections.

, It further consists in the peculiar corn struction of the connecting menus, and still further in certain details ol' construction es similar to Ifig. 1, showin.;A a modi'licd form of connecting; means; Fig'. -1 n View siniil'r to Fig. 1 snowing a still 'further modification; and iff'. 5 is n vert ical central section the construction of conduit shown 5. i.

Yi'ith reference particolari)v to the construction. of conduit shown in Fig. 1. A and B represent tivo abutting sections formed erich of sheet metal, the meeting edges which are riveted to forni cylindrical sections. Each of these conduit sections is provided at its meeting edge with fr segmental flange, as C, in this instance a metal band extending preferably half Way about the conduit Seci combination of abutting sections provided tion and riveted thereto. These bands ere also provided with lateral offset portions al; their ends, indicated by the reference-letter I), which when the conduit sections are ar ranged in place register one with the other, .and these registering portions are clamped by any suitable Ineens, as bolts E. A conduit formed in this manner is especially adapted for sewer \\'orl;,--as a sewer pipe, l'or the reason than the meeting ends of the conduit sections abut, and thcinterior ot' the conduit is of uniform diameter throughout its length, there being no overlapping of the sections.

In Fig. 3 I have shown the conduit sections as inade from corrugated metal and the segmental llene-es at the meetiuc' ends of the sections I11 and G irtegral with the sections, the letter being cut awry et their ends for this purpose. I have also shown lateral olli set portions H formed by angle-shnped pieces or" metal riveted to the ends of the flanges, these oilsets beingl adopted to register and to he clamped together in the saine manner as those shown in Fig. 1.

In Fig. 4 a further modiiciition of rn improved conduit is shown, thc section icing forn'ied preferably of cc-rrugntcd metal and the segmental flanges being integral. The ronduit sections in this instance, however, :1re adapted to bebrought into engaffement in such s manner that each flange rfi Aoverlap a segmental section or portion of the adjoining conduit section in the'menner indi cated in Fig. 5, producing a rigid construe tion of conduit. Any torni of clamping means muy be employed for hoiding the sections together, but I preferably use bonds a and i), with suitable band tiehtenersf-cs for instance a turn-buckle c,-1n ecc-h instance for clamping the band circumferentia-lly about the conduit. These bends, as shown in Fig. 4, are adapted each to pass about the body portion of one conduit section and cir cumf'erentially about the segmental liange of the adjoining section, thus tightly clamping the sections in place. This form of conduit .is designed more particularly for culvert Work Where the sections are of considerable size and a tight joint between the sections is not absolutely essential.

YVVhet I claim es my invention is,-

2. In a sectional metallic conduit, the combination of tiro abutting conduit sections provided each with e, segmental flange,

the ilungcs being oppositely disposed, und each overlapping e segmental portion of the adjoining section, and clamping means for the sections extending circumferentially about the flanged portions.
